The radio aerial is integrated into the rear window, which is bonded in position with a special adhesive; if faulty, a new rear window must be fitted. For the navigation, telephone, and auxiliary heater telestart aerial, it is located at the rear of the roof panel, requiring the trim from the C-pillar to be removed first. After undoing the screws and removing the two rear grab handles from the headlining, the rear of the headlining can be carefully lowered to disconnect the wiring, noting the colour-coded connections: violet for the telephone, blue for the navigation system, and the remaining connector for the auxiliary heating remote control. The securing nut should be unscrewed to withdraw the aerial base from the roof, holding the base to prevent rotation and scratching the roof panel while recovering the rubber spacer. Refitting involves reversing the removal process, ensuring the two guide lugs on the rubber spacer are correctly located in the aerial base. The aerial amplifier is fitted to the top of the tailgate behind the inner trim panel; the ignition and all electrical consumers must be switched off before removing the inner tailgate trim panels and disconnecting the amplifier wiring connectors. After undoing the retaining screw, the amplifier can be withdrawn from the tailgate, with refitting being a reversal of removal. The aerial module is also fitted in the tailgate behind the inner trim panel, requiring the ignition and all electrical consumers to be switched off before removing the inner tailgate trim panel. The securing clips must be released to disconnect the module wiring connectors, followed by removing the two upper mounting bolts and slackening the lower mounting nuts to withdraw the module, ensuring the small wiring connector at the rear is disconnected carefully to avoid damage. Refitting is again a reversal of removal.
